摘要:
A process for forming an activated carbon fiber filter for removing viruses from liquids is provided. The process includes selecting a plurality of activated carbon fibers, placing the activated carbon fibers in a hollow form open at least one end, and applying a predetermined compressive force to the fibers along the axis through the hollow form parallel to the direction in which the liquid will pass until the fibers are densely and uniformly packed within the form.
摘要:
Processes for forming a filter material are provided. The processes include the steps of coating a filter particle with a lignosulfonate, carbonizing the coating, and activating the coating.
摘要:
A composition of polyolefin, ester additive, and hyperbranched polymer with improved tensile energy-to-break value compared to polyolefins wihtout the hyperbranched polymer. The concentration of the hyperbranched polymers can be between about 0.1% and about 10% by weight of the polyolefins. The polyolefins have a melt flow index of about 14 g/10 min or greater.
摘要:
Disclosed is a method of removing hormone(s) from a liquid, the method comprising contacting the liquid with a filter comprising activated carbon fibers. Also disclosed is an article of manufacture comprising (i) a filter comprising activated carbon fibers and (ii) instructions informing a user that the filter is capable of removing hormone(s) from I.
摘要:
The present invention relates to selecting dispensers having optimal spray patterns for use together with aqueous wrinkle removal and/or reduction compositions to minimize the potential to stain fabrics and significantly reduce drying time associated with aqueous-based wrinkle control compositions. The present invention also relates to wrinkle control compositions suitable for use in dispensers with optimal spray patterns and articles of use including instructions for use. The present invention also relates to methods of use for wrinkle control compositions in dispensers with optimal spray patterns.
摘要:
The bleeding of lignosulfonates from lignosulfonate-treated substrates when contacted under humid conditions is reduced by rendering the lignosulfonates water-insoluble via reacting them with an amine polymer-epichlorohydrin adduct containing at least one quaternary ammonium group under acidic conditions.

摘要:
The present invention relates to a process of using steam to achieve simultaneous impregnation and drying of lignocellulosic material to improve the strength of lignocellulosic material and to reduce the number of serial processing steps. The steam may be either indigenously generated by way of a heated press or heated nip, or the steam may be externally applied.

摘要:
The strength of lignocellulosic materials is improved by treating them with water-soluble strengthening agents containing sulfonic units, and rendering these agents water-insoluble by reacting them with compounds containing azetidinium rings. Thus, a substantial reduction or elimination of the bleeding of said strengthening agents from the lignocellulosic materials when touched with wet hands or contacted under humid conditions is achieved.
